Congratulations to Canadian teens Isabella O'Brien, 13, and Calvin Rieder, 18, on becoming finalists in the Google Science Fair!

Sometimes the biggest discoveries are made by the youngest scientists. They’re curious and not afraid to ask, and it’s this spirit of exploration that leads them to try, and then try again. Thousands of these inquisitive young minds from around the world submitted projects for this year’s Google Science Fair, and today we’re thrilled to announce the 20 Global Finalists whose bright ideas could change the world.

From purifying water with corn cobs to transporting Ebola antibodies through silk; extracting water from air or quickly transporting vaccines to areas in need, these students have all tried inventive, unconventional things to help solve challenges they see around them. And did we mention that they’re all 18 or younger?
